LIZ SCOTT: Shoulders tall. Move your shoulders around a little bit. Beautiful. Now can I get you to put your hands on your ribcage? So not on your waist, which is down here, but just up on your ribcage. And you breathe out. And now, take a deep breath in. You should feel your ribs expand. That's it. And breathe out. And, again, breathe in and out. Breathe in through your mouth. Breathe in and out.

Don't lock your knees. Make sure that your knees can still move. All right, we're going to do some breathing. [snapping the pulse] This is going to be our pulse, and I'm going to get you to breathe in for 4 counts and out for 4 counts. And I want you to do it with your hand. So this is the air. You're going to breathe-- bring your-- the air in, and then you're going to push the air away.

So we're going to count 4 beats, and we're going to breathe in for 4 and out for 4. And then, I'm going to change the number of counts for in and out. Just keep listening and keep breathing. So good posture. Breathe out first for me. OK, here we go. This is our pulse. [snapping the pulse] Breathe in for 4 through your mouth. Go, breathe in. Pull the air in. Use your hand, 2, 3, 4, and then out for 4. 1, 2-- feel the pressure. Good. Breathe in for 3. Slowly pull the air in, 2, 3.

Just stop for a second. So this is not pulling air in. There's no resistance there. You want to actually drag-- use the muscle in your arm. You want to feel the air pressure. Imagine that your arm is in water. Now-- that how heavy it is to move your arm through water or a massive tub of honey, which you might go swimming in. I don't know.

[students laughing]

If you-- If you own lots of bees. So you want to feel that weight. So this-- during this movement with-- you can see that there's nothing. I'm not feeling any pressure at all. I want you to drag the air in and push it away. Give it a try. Pull the air, drag it heavy through water, and push away. Drag it in and push away. [snapping the pulse] OK, good. Here we go. Ready breathe in for 4. Pull it in.

1, 2, 3, 4, and out. So you're breathing right down to your toes. Breathe in for 3-- in for 3, out for 4. 2, 3, in for 2, out for 4. Out for 4, push the air away. Keep it going. 3, in for 1, out for 4. Out for 4, 2, 3. Again, in for 1, out for 4. 1, 2, 3, good.

In for 4 slowly. Same amount of amount air, 2, 3, and out for 8. Keep it even. Keep the air moving. Keep your arm moving, 5, 6, 7, 8. In for 3. Out for 8, 1, 2, 3, 4, 5, 6, 7. In for 2. Out for 8. Even air. 3, 4, keep it going, 5, 6, 7. In for 1. Out for 8, 2, 3, 4, 5. Again, in for 1. Out for 8. Silent breath, 2, 3, 4, 5, 6, 7, 8, and relax. Good.

When you did the silent breath, you're consciously relaxing here. It's very easy when we're thinking about a whole lot of other things to [heavy breathing]. Remember, yesterday, we talked about the whole sounding like a choir of asthmatics. Make sure that this-- when you take that breath that you think of relaxing it and open your throat, so that you can take that nice silent breath.
